Quick Thoughts: Bluer Than Blue—Investment Implications

The 2026 US midterm results will increase policy uncertainty and dispersion across industries without displacing earnings, real interest rates and the long-term AI investment cycle as the main market drivers.

• Democrats are projected to control both congressional chambers and win governorships in Texas, Georgia, Ohio and Iowa, while affordability concerns over housing, health care, energy and everyday expenses are likely to remain politically important through 2028.
• Franklin Templeton Institute's review of the nine midterm elections from 1990 to 2022 found that the S&P 500 gained an average of 14.5% in the following 12 months, with positive returns in every period, although divided government does not imply fiscal discipline and federal deficits and Treasury issuance are likely to persist.
• AI data-center expansion will remain structurally supported, but state-level opposition over electricity prices, water use and infrastructure costs could alter project locations, delay construction and increase costs; power generation, transmission, electrical equipment and grid infrastructure should benefit, subject to regulatory risks.
• Health care, financial institutions, defense contractors and energy companies may face material changes in scrutiny, spending priorities, regulation, permitting or federal incentives, while governors and state regulators could affect utilities, infrastructure, taxation, manufacturing incentives and municipal-bond credit more immediately than Congress.
• Democratic control could delay comprehensive cryptocurrency market-structure legislation after the CLARITY Act failed to advance in September, although the GENIUS Act's federal framework for payment stablecoins remains law; near-term volatility may rise even as eventual clarity supports institutional adoption and tokenization.
• The current backdrop differs from earlier midterms because AI is supporting growth and earnings while creating electricity tensions, the Iran conflict is pressuring energy markets and inflation, and the Federal Reserve has resumed raising rates; higher Treasury yields have been driven mainly by real rates, increasing capital costs and potentially weighing on 2027 growth and earnings.

Takeaway: Investors should focus on state-level policy, sector dispersion and the effects of real rates and AI investment rather than treating the election as a decisive market-wide signal, while distinguishing political noise from policy changes that can materially affect returns.
